Abstract: In apparatus for reducing interference in a first signal (102) caused by a second signal (103) the first signal is tested (in 106) to determine how much interference can be tolerated. During portions of the first signal which can tolerate a large amount of interference, the amplitude of the second signal is increased (in 105). During portions of the first signal that can only tolerate a small amount of interference, the amplitude of the second signal is decreased. The average amplitude of the second signal is large enough to provide an acceptable bit error rate or signal to noise ratio, yet small enough not to substantially corrupt the first signal. In one embodiment, the technique is employed to allow transmission of additional data on a television channel.

Abstract: Method for time-scale modification ("TSM") of a signal, for example, a voice signal, wherein starting positions of blocks in an input signal, referred to as analysis windows, are varied and an output signal is reconstructed by overlapping analysis windows using fixed window offsets, i.e., the duration of overlap between analysis windows is fixed during reconstruction. This is done by searching for segments of the input signal which are similar to the previous portion of the output signal. In one embodiment of the present invention a cross-correlation is used as a similarity measure to evaluate such similarity and the cross-correlation uses a fixed, predetermined minimum number of samples. The starting position of the analysis window which results in the greatest similarity in overlapping regions is determined as the starting position which provides the largest value of cross-correlation in the overlapping regions. Several cross-correlations are evaluated by shifting the analysis window over a predetermined number of samples, removing the first shifted samples in the evaluation each time, and using the same, predetermined number of samples in the evaluation to determine the "best" starting position for an analysis window. Finally, the predetermined number of samples from the beginning of the analysis window are averaged with the predetermined number of samples from the end of the previous portion of the output signal and the remaining samples in the window are appended to the averaged segment of the previous portion of the output signal.

Abstract: The invention relates to a 3-phase charge-coupled imaging device which is operated in the interlace mode. During integration, voltages are applied to the clock electrodes such that charge is integrated below the same set of electrodes each time. The signal charges of the first field are formed in that 3/4 portion of the charge in each picture element is augmented by 1/4 portion of the charge of the preceding picture element, while the signal charges of the second field are formed in that the said 3/4 portion is augmented by 1/4 portion of the charge generated in the following picture element. These summations may be carried out in the sensor itself in that the charge packages are shifted to the left and right during integration. The flicker which is usually the result of interlacing is very strongly reduced in this way.

Abstract: An optical disc apparatus includes a rotary encoder (14) for detecting a revolution of a spindle motor (12) that rotates an optical disc (11). A counter (16) generates a timing pulse (P3) per revolution of the optical disc (11) in synchronism with an output timing pulse (P1) of the rotary encoder (14).
